Abstract

The present invention discloses a fine polishing wheel used for metal products, which is prepared by the following raw materials: (a) materials: 100 portions of No.800 carborundum powder, more than 600 mesh; 120 to 146 portions of PF resin; 120 to 240 portions of silicate filling, more than 600 mesh; 25 to 32 portions of NBR rubber powder; 7 to 12 portions of red ferric oxide, more than 320 mesh;3.2 to 4 portions of lubricant; (b) the preparation method: (1) after being processed by coupling agent, the No.800 carborundum powder is orderly uniformly mixed with the PF resin and the silicate filling, the NBR rubber powder and red ferric oxide, and the lubricant; (2) the mixture of the first step is poured into a mould for cold press molding; (3) the formed roughcast is placed into an oven and heated, then heating is stopped, and after self cooling, a finished product is taken out of the oven. The present invention has the advantage of obvious polishing effect on nonferrous metals, the finish of the surface of the polished metal product can reach over 12-grade, the present invention is particularly applicable to the polishing of stainless steel products, and the prior metal-polishingwheel can hardly reach the effect realized by the present invention.

Description

The precision polishing wheel that is used for metallic article

Technical field

The present invention relates to polishing wheel, especially relate to the precision polishing wheel that is used for metallic article.

Background technology

Hardware is non-ferrous metal member or goods especially, and as stainless steel products, alloy aluminum goods, copper product etc., therefore its finished product need polish bright processing to reach certain glossiness owing to will keep the metal primary colors; Therefore employed in the market polishing wheel, though can make metal component surface reach certain fineness, glossiness is used for need spraying paint or the polishing of plastic-blasting hardware to appearance not enough.And keep the hardware of primary colors for needs, and often adopt the minute surface grinding machine to polish bright processing, this has not only increased the polishing difficulty of irregular metallic article, and the while has also been improved processing charges.

Summary of the invention

The object of the invention is to provide a kind of precision polishing wheel that is used for metallic article that uses simple operation.

For achieving the above object, the present invention can take following technical proposals:

The precision polishing wheel that is used for metallic article of the present invention is prepared from by the following weight parts proportion raw material:

A, raw material proportioning:

No. 800 sic powders that 600 orders are above, 100 parts; PF resin 120-146 part;

The silicate fillers that 600 orders are above, 120-240 part; NBR rubber powder, 25-32 part;

The iron oxide red that 320 orders are above, 7-12 part; Lubricant, 3.2-4 part;

B, preparation method:

The first step, No. 800 sic powders through after the coupling agent treatment with PF resin, silicate fillers mixing; Add NBR rubber and iron oxide red mixing then; Add the lubricant mixing at last;

Second step, the compound that the first step is obtained place cold moudling in the mould, pressure 1.4-1.9MPa;

The 3rd step, the blank of moulding put in the baking oven heat, heating process is: 80 ℃, and 2h → 100 ℃, 2h → 120 ℃, 1h → 140 ℃, 1h → 160 ℃, 1h → 170 ℃, 3h;

Stop heating then, treating to come out of the stove after nature cools off gets final product.

Described raw material proportioning is:

No. 800 sic powders that 600 orders are above, 100 parts; 146 parts of PF resins;

The silicate fillers that 600 orders are above, 240 parts; NBR rubber powder, 32 parts;

The iron oxide red that 320 orders are above, 12 parts; Lubricant, 4 parts.

Described raw material proportioning also can be:

No. 800 sic powders that 600 orders are above, 100 parts; 120 parts of PF resins;

The silicate fillers that 600 orders are above, 120 parts; NBR rubber powder, 25 parts;

The iron oxide red that 320 orders are above, 7 parts; Lubricant, 3.2 parts.

Described raw material proportioning also can be:

No. 800 sic powders that 600 orders are above, 100 parts; 132 parts of PF resins;
